IV. ENVIRONMENTAL MITIGATIONS MEASURES IMPLEMENTED IN THE REPORTING PERIOD

76. It had been more than seven years since preparing the EIA during the PPTA, some contents and requirements in the EIA are not suitable for the current situation. In consideration that Xi'an is the World famous history city, The LIEC, together with the Environmental Supervision Co. updated the EMP and environmental monitoring plan. The main mitigation measures implemented during construction are highlighted below:

77. Noise control: Construction activates are prohibited between 22:00 – 6:00. In noise sensitive areas, such as schools, hospitals and residential areas, low noise machineries must be used, and construction time must be strictly controlled; placement of temporary fence hoards or noise barriers to shield noise sources during construction if necessary.

78. Dust control: Watering of road and construction site during windy days; Cover construction material/earth transport trucks before leaving the site; The trucks must follow the route approved by the environmental supervision Co. and local EPB; Particular attention must be paid to dust suppression adjacent to sensitive receptors such as schools, hospitals or residential areas; materials should be stored in appropriate places and covered.

79. Solid waste: The domestic waste was timely collected and carried to the places appointed by local EPB and public sanitary authority; the construction and demolition wastes were stacked uniformly on the construction site and transported to the construction waste disposal site designated by local EPB and public sanitary authority in time.

80. Waste Disposal: All waste produced by the project should be handled in accordance with the requirements of the national environmental protection administration and the IA. All the construction vehicles and machineries should be periodic maintained; the oil and lubricating oil were not contaminated the ground and river; install the oil-water separator in the washing and refueling area; storage of fuel in quarantine area.

81. Water and wastewater: Wastewater during construction must be treated and controlled, recycled water was used to spray for dust control; Latrines and seepage pits was installed in all camps;

82. Traffic congestion: Contractors must consider impacts to traffic during construction. A traffic control and operation plan was prepared and be approved by local traffic management administration prior to any construction; the plan includes diverting or scheduling construction traffic to avoid morning and afternoon peak traffic hours, regulating traffic at the road crossings, building interim roads, selecting transport routes to reduce disturbance to regular traffic; reinstating the roads and opening to traffic as soon as completion of the construction.

83. Emission from construction machinery: Asphalt plants and mixers were sited as far away as possible (at least a minimum of 200 m downwind) from the nearest residential areas and other sensitive receptors; Vehicles and construction machinery were properly maintained and complied with emission standards.

84. Soil erosion: This is a city construction Project dealing mainly with paved and covered surfaces in commercial, industrial and residential locations. Soil surfaces exposed to erosion were minimal. In this situation a Soil Erosion Prevention Plan was not required under PRC legislation. The soil erosion intensity of this project was slight, and the impacts were further reduced by appropriate site management. An erosion protection plan was developed and approved prior to construction; existing surface where no construction activity was planned was preserved; the stable surface where activity was planned for a later date was temporarily preserved; disturbed surfaces, such as borrow and fill areas, compacted pipeline trenches and cut banks was properly sloped and/or revegetated to minimize erosion; limit construction and/or material handling during rain events and high winds to minimize wind erosion; construct intercepting ditches and drains to prevent outside runoff entering construction sites, and divert runoff from sites to existing drainage system or ponds; reinforce the disturbed area after construction(paving or landscaping and planting of medium strips, verges and temporary access roads ).

85. Work camp health and hygiene：The domestic sewage in each construction camp is discharged into the municipal sewage pipe network after being treated by the septic tank, the domestic garbage is collected and transported by the sanitation department in a unified way, and the cooking fume in the canteen is discharged after being treated by the cooking fume purifier. The building materials were stacked neatly, stored in proper place and covered.

86. Cultural heritage protection：The implementation of the project minor affected the environmental features of the relevant cultural relics and sites. During the construction phase of the project, protective measures were taken in accordance with the approved Construction Control Plans (CCP) for construction sites to avoid the impact on the relevant cultural relics and sites, try to keep the style and color of the construction project consistent with the style and color of the cultural relics and sites, and reduce the damage to the environmental features of the cultural relics and sites. The construction plan scheduled inspections of archaeological potential at each major construction stage involving earthworks. Any discovery of buried relics should be referred to the Shaanxi Provincial Bureau for Cultural Relics for advice and assessment, and construction work should be also interrupted during this process. So far, the civil works had been completed and no any discovery of buried relics occurred. Other mitigation measures included the following: (i) The building scale, height and design are in conformity with that of the relic sites; (ii) construction avoided the use of machines or techniques which could generate high levels of vibration to avoid potential damage to tombs; and (iii) construction site drainage and effluent, as well as stormwater drainage from the hub during operation, were directed away from the Prince Jian and Prince Qin Mausoleum sites.

87. Other EHS requirements and measures identified in EIA and related environmental risk control measures: All mitigation measures were implemented during trial operation, such as dust and noise control at project roads. Some key impacts or risks were fully considered, such as the potential risks might be caused by explosion hazards from petrol/diesel and CNG filling stations. The gas filling station involved in the project is expected not a major risk source, and it is generally impossible to cause casualties, but the protection distance was set. The distance between oil tank and important public buildings is less than 50m, and that between general residential areas is less than 20m. In addition, the EHS management plan was updated and aligned with relevant government regulations and guidelines on COVID-19 prevention and control, or with international good practice guidelines as updated in the future. 4 The plan was reviewed by the supervision consultant in consultation with local public health inspectors, local medical officers, or other relevant health specialists, with a recommendation forwarded to the EA for clearance. The plan includes COVID-19 prevention and control measures, including disinfection/cleaning of offices, construction sites and labor camps, on-site temperature checks, social distancing measures, mandatory use of personal protective equipment such as facemasks, provision of handwashing stations and hand sanitizers etc., and procedures to be adopted in the event any worker is infected with COVID-19. During this reporting period, COVID-19 prevention and control measures were taken following the above EHS management plan, PRC government regulations and guidelines or international good practice guidelines as updated time by time.

88. It is estimated to spend CNY630,000 for the pre-construction phase, CNY680,000 over the construction period and CNY 2,737,000 in the initial operation phase, respectively. The spreadsheet will be prepared for Project Completion Report preparation with the actual expenditures on environmental management scheduled in 2nd half 2020. During the reporting period, the Environmental Supervision Co., together with the LIEC conducted 20 times’ site environmental inspections, environmental monitoring and environmental protection publicity. During the inspection, the Environmental Supervision Co. and LIEC found some environmental issues on the construction sites that fail to accord with the EMP and PRC environmental regulations and good practices. For solving the problems, the EMP coordination meeting were held with contractors, CSCs and IA, and three rectify notices to contractors were issued (Table 5). After the contractor corrected its fault, an additional

VI. PUBLIC CONSULTATION, GRIEVANCE REDRESS MECHANISM

92. In accordance with the guidelines of the EIA and the ADB's SPS requirement, public participation was carried out in each subproject during the EIA period. During construction stage, the PMO/PIUs/contractors conducted continuous consultation with nearby communities. A further public consultation after the project completion will be undertaken by the PMO in late 2020, regarding to effectiveness of mitigation measures, impacts of operation, comments and suggestions, and survey on public satisfaction. Those consultation results and assessment will be documented the borrower’s project completion report.

93. Environmental protection publicity. It is a very important work of environmental supervision to carry out environmental protection publicity in construction site. In the daily environmental supervision work of the project, the environmental supervision personnel always put the environmental protection publicity in an important position, made serious efforts to do a good job of environmental protection publicity of the project, and promoted the development of environmental supervision work.

94. Using site meeting to publicize environmental protection concept. Since entering the project, the environmental supervision has made full use of the construction site coordination meeting and tripartite site meeting to carry out the publicity and implementation of environmental protection concept. In the meeting, the daily inspection and implementation of environmental protection measures on the site of environmental supervision in the near future were reported; the existing environmental problems in the current construction site were analyzed, and specific treatment measures were determined; the spirit of documents of EPB at all levels and higher competent departments of environmental supervision were conveyed; it was repeatedly emphasized that the construction unit should pay attention to the environmental protection education and training of on-site construction personnel as well as construction safety education to further improve the environmental protection awareness of the construction unit 's management and ensure that the impact on the surrounding area environment is minimized in the daily construction process.

95. During the PPTA, the GRM system was established in accordance with ADB SPS. And it was provided to the affected persons. The contact persons for different GRM entry points, including contractors, CSCs, the EPB, PPCU, etc., was identified prior to construction. The contact details for the entry points (phone numbers, addresses, e-mail addresses) were publicly disclosed on information boards at construction sites. There was no complaint filed for environmental issue in the report period (January to June 2020). The details of contact information for GRM are summarized in Table 8 below.

VII. ISSUES, CORRECTIVE ACTIONS, RECOMMENDATIONS

96. EMP implementation in the reporting period is generally satisfactory. Domestic EIA preparation and approval for scope of change, and other environmental approval documents, such as SEPP, traffic management plans, etc. had been obtained timely. The environmental mitigation measures for the scope of changes had been incorporated and optimized. Verification of loan covenant in respect of EMP embedding in bidding documents and contract clauses was undertaken through continuous environmental supervision and monitoring as well as environmental publicity. All the contractors have assigned staff in charge of daily environment, health and safety inspections; The Environmental Supervision Co. conducted 19 times on-site environmental supervision and prepared monthly environmental supervision reports, which were timely submitted to the IA and PMO and the consultants. The IA established EMU and the GRM; no complaint has been filed for environmental issue in the report period.

97. During site visit, the Environmental Supervision Co. found that i) Unorganized piles of construction waste is not cleared and transported in time in Xi'an North Railway Station Bus Hub. ; ii) Poor implementation of dust pollution prevention and control. No active implementation of emergency response mechanism for heavy pollution weather and not fulfill the night construction procedures and earthwork backfill procedures. Poor management of the outsourced earthwork backfill vehicles, may have a risk of related environmental pollution complaints;iii) No vehicle flushing equipment at the entrance and exit of Western Keji II Road (West 3rd Ring Road-Zhangba North Road).Air pollution prevention and control measures at the construction site and emergency response mechanism for severely polluted weather are not implemented.. The Environmental Supervision Co., the LIEC, the IA and PMO required the contractors to correct the above problems timely, and to strictly implement all the mitigation measures defined in the EMP. The contractors conducted the correcting measures after receiving the rectification notices and reply to the IA and the environmental supervision firm showing the measures were timely taken.

98. The pending issues including: (i) due diligence study on the subcomponents completed and assessment on the compliance of the EMP implementation, and (ii) evaluation on environment benefit, such as emission reduction from traffic control program, integration of road and parking facilities, CNG fuel adoption, will be incorporated to PCR preparation, which is scheduled in the 2nd half of 2020. In the meantime, the following time-bound action plans are formulated and agreed by the PMO/IAs as the following:

(a) Mitigation measures taken during construction and operation should be systematically recorded then summarized. The summary will be reflected in the borrower’s project completion report which is expected to be prepared in the 2nd half of 2020.

(b) Noise barriers were built along Zhuhong Road-North 2nd Ring Road Interchange, Zhuhong Road-Fengcheng IV Road Interchange, and Fengcheng VIII Road-Taihua

Road Interchange (see Appendix 1)6. The options of specially designed and built noise barriers and sound-proofing for windows and ventilators proposed at the EMP for sensitive receptor sites (mainly residential and dormitory buildings) along portions of the new roads and interchanges will be reviewed and determined according to actual operational noise testing results at the domestic completion environmental check and acceptance in the 2nd half of 2020. And

(c) Actual investment on environmental protection and mitigation measures should be sorted out and summarized in the aforementioned borrower’s project completion report, that will also include quantitative (as possible) and qualitative environmental benefits analysis for environmental protection, including the emission reduction from traffic control program, integration of road and parking, and CNG fuel adoption.

APPENDIX 1 - The DOMESTIC Environmental Supervision Report

6 During this reporting period, most subprojects were at commissioning stage with relatively lower operation load. The whole project operational monitoring (particularly for noise under certain traffic flow scenario) will be undertaken at domestic completion check and acceptance stage, which is scheduled in the first half of 2021. By then, noise barriers and sound proofing for windows and ventilators for sensitive receptor sites will be installed according to actual impact status.

2.2 Implementation of Environmental Supervision Plans

2.2.1 Process of Environmental Supervision According to the Environmental Supervision Regulations for Construction Projects (DB61/571-2013), working process of project environmental supervision can be divided into preparation, implementation and transfer, as Fig.2.2-1 indicates.

Fig. 2.2-1 Flow Chart of Construction Project Environmental Supervision 2.2.2 Works of Environmental Supervision (1) Information Collection Environmental supervisors have access to Environmental Impact Assessed (EIA) documents and official approvals, construction designs, feasibility reports, construction organization designs of construction undertakers, environmental management system certification materials, environmental supervision standards of construction project and other technical information. The results show that EIA documents and official approvals of the project, construction designs, feasibility reports, construction organization designs of construction undertakers, and environmental management system certification materials are completed and perfect. As for the environmental pollution occurred during construction periods, environmental supervisors put forward treatments and control measures.

Environmental supervisors assist the construction undertakers to perfect the environmental protection chapters of construction organization design documents as well as improving the environmental management system, making these documents in compliance with the EIA documents and official approvals. Main documents and main contents checked by environmental supervisors are shown in Tab. 2.2-1, in which all the information has been collected. During the construction period, environmental supervisors access any materials needed.

No. Documents Major Contents

Combing with actual construction progress, environmental supervisors further clarify the pollution

precautions and supporting environmental protection EIA documents and official 1 facilities. Once the construction content is changed, approvals supervisors shall remind the construction undertakers to redo the EIA. Construction undertakers have entrusted EIA organizations to assess the environmental impacts. Environmental supervisors shall clarify the actual scale, alignment, composition, investment and environmental investment, environmental protection facilities, and 2 Construction designs ecological recovery measures, and recheck the design documents of the project to implement requirements of EIA documents and official approvals. Environmental supervisors shall verify the Construction organization implementation of measures and requirements proposed 3 designs of construction in environmental chapters of construction organization undertakers (rechecking) designs, as well as the establishment of environmental protection system on the construction site. Environmental supervisors shall collect and assist the Environmental management construction undertakers to perfect the environmental 4 system certification materials management system and the staffing of environmental supervisors Environmental supervision Environmental supervisors shall comprehend the method 5 standards of construction and key points of traffic project environmental project supervision.

Relevant laws and regulations Environmental supervisors shall comprehend relevant 6 of environment supervision laws and regulations of environmental supervision. The Feasibility Report of ADB According to the project feasibility report (interim Loan Xi’an Urban Road-Net adjustment version and the final revision), combined 7 Improvement Project (Interim with the actual construction content of the project, the Adjustment Version. The Final environmental supervisors should timely adjust the Revision) environmental supervision works. (2) Patrol and Inspection Environmental supervision site patrol inspection refers to that the environmental supervisors and technical personnel carry out daily irregular supervision and inspection on the environmental conditions and environmental protection measures of the project construction, which is the main method of environmental supervision works. In the first half of 2020, environmental supervisors have totaled 17 daily inspections. During the process of daily inspection, the main existing environmental problems discovered through environmental supervision are as follows: 1) Western Keji II Road (West 3rd Ring Road-Zhangba North Road) During the construction of the southern half of the Western Keji II Road (West 3rd Ring Road-Zhangba North Road), there was problems of inadequate coverage of earthwork and white ash during the construction process. Environmental supervisors have required the construction undertaker to cover the earthwork, white dust, and other dusty materials, strengthen the implementation of air pollution control measures at the construction site, and ensure that construction dust is minimized. The construction has covered the dusty materials such as earthwork and white ash in accordance with the requirements. 2) Fucun East Road Car Park During construction of Fucun East Road Car Park, construction wastes and domestic waste on site were not cleaned up in time. Environmental supervisors have required the construction undertaker to sort and pile up domestic wastes and construction wastes in the field in a timely manner, promptly remove and transport them, and ensure the environmental quality of the construction site. The construction undertaker has cleared and transported construction waste and other wastes in accordance with the

requirements.

3) Xi’an Aerospace Base Transportation Hub Bus Stop During the construction of Xi’an Aerospace Base Transportation Hub Bus Stop, the floating soil on those unhardened roads was thick, and some earthwork on the site was exposed and piled up. Environmental supervisors have required the construction undertaker to water the site more often and cover the exposed earthwork to ensure the implementation of various requirements for the prevention and control of dust pollution. The construction undertaker has arranged personnel to cover the exposed earthwork of the site, and regularly spray water to reduce the dust on the unhardened roads. 4) Xi’an Xigao Bus Company Bus Stop The major environmental problem in the construction process of Xi’an Xigao Bus Company Bus Stop was the exposed piles of earthwork on the construction site. Environmental supervisors have required the construction undertaker to cover the exposed earthwork in time to minimize the dust pollution generated by the construction. The construction undertaker has taken coverage measures on the exposed earthwork. 5) Matters Needing Attention in the Preparation of Interim Adjustment EIA Report Based on the the Environmental Impact Statement and the General Feasibility Report of ADB Loan Xi’an Urban Road-Net Improvement Project (midterm review report, The Final Revision), environmental supervisors compare the actual construction contents of the project and require the construction undertakers to provide the original EIA documents and approvals, report forms of sub-projects, and registration forms to all the EIA institutions in a timely manner. Also, environmental supervisors should conduct site surveys of all projects (including completed projects), compare the differences and changes in uncompleted projects and environmental protection measures in the new EIA documents, and propose optimal plans and schemes. Finally, environmental supervisors should demonstrate the environmental protection measures of completed projects. Especially when the built projects have measures that are inconsistent with the original EIA measures, it is necessary to demonstrate

whether these measures of built projects can meet the requirements of environmental protection laws, regulations, and specifications. The IAs have entrusted EIA organizations to assess the environmental impacts. (3) On-site records On-site records refer to the supervision logs and images recorded by environmental supervisors during the supervision process, which are the most important and basic data for environmental supervision. According to the situation of each inspection and the requirements of the environmental supervision implementation plan, the environmental supervision shall faithfully prepare the environmental supervision logs. The major contents include: a brief description of the construction content of each contract section of the project; a brief description of the environmental supervision work (review, approval, inspection, side supervision, instructions, and meetings); a brief description of the clarification or handling of project-related issues. In the first half of 2020, environmental supervisors have totaled 17 environmental supervision logs. (4) Site Supervision Construction site supervision refers to the continuous supervision and inspection towards some of the important environmental problems conducted by supervisors, which is an important supplement to the patrol and inspection work. Solutions of serious environmental problems discovered during the process of project environmental supervision, precautions and protections of the contaminates that have greater impact on the environment inside the construction area and the protections of some important cultural relics are under site supervision, and are recorded on the Site Supervision Recording Sheets. On Jun. 1st, 2020, the environmental supervisors conducted one site supervision on the installation of the septic-tank in the construction site of Fucun East Road Car Park. Environmental supervisors have collected septic-tank construction drawings, inspection reports, qualification certificates, and other relevant materials. (5) Issuance of Instruction Documents Instruction documents adopted in daily project environmental supervision mainly include: environmental supervision communication sheet and notice. During the patrol

and inspection, environmental supervisors first notify the construction undertakers about the environmental pollution problems orally, if the construction undertakers do not rectify, environmental supervisors will send a communication sheet to the construction undertakers, requiring them to rectify and implement, while the sheet will be copying to the general Contractor and Owner, and the environmental supervisors will recheck and confirm the rectification. When the environmental problems are relatively serious during the construction process, or in the case of sudden environmental problems, the environmental supervisors will check the situation on-site and then send communication sheet to construction undertakers, requiring them to rectify and report the rectification to environmental supervisors in written form, and environmental supervisors will report the rectification to the Owner. Our company implements three-level audit management on the supervision documents and reporting materials. Environmental supervision logs, supervision communication sheets, rectification notices and other on-site supervision documents are audited by environmental supervisors, supervision engineers and project director of the project department. Monthly reports, special reports and supervision reports are audited initially by the environmental supervision project department, followed by the company expert group, then the chief engineer of environmental supervision, and finally confirmed and issued by the company. For the environmental problems in the daily constructions of the projects and the need to provide relevant environmental protection materials, the environmental supervisors have sent a total of 4 environmental supervision communication sheets in the first half of 2020. The major contents of environmental supervision communication sheets are as follows: 1) 2020-001 Communication Sheet (May 13th, 2020) SCEGC Mechanized Construction Group Company LTD. is responsible for the construction of the Western Keji II Road (West 3rd Ring Road-Zhangba North Road). During the inspection, the environmental supervisors found that the earthwork in the construction area was barely piled without any coverage. Environmental supervisors have required the construction undertaker to fully cover the exposed earthwork in the 56

construction area to minimize construction dust pollution and ensure the implementation of various requirements for dust pollution prevention. 2) 2020-002 Communication Sheet (May 15th, 2020) Shaanxi Hongyuan Construction (Group) Co., Ltd. is responsible for the construction of Fucun East Road Car Park. At present, the project has basically entered the final stage.

4) 2020-004 Communication Sheet (Jun. 5th, 2020) 57

The Environmental Protection Department has announced that the theme of 2020 National Environmental Protection Day continues to be “Beautiful China, I am A Doer”, the “Make China More Beautiful” as the theme song of the Environment Day, and the theme practice sign of “Beautiful China, I am A Doer” as the sign of Environment Day. All localities should follow the requirements of overall promotion of the prevention and control of the COVID-19 pandemic and the ecological and environmental protection of economic and social development, closely follow the propaganda theme, study and propagate president Xi Jinping’s ecological civilization thought in an in-depth manner, vigorously promote ecological culture and ecological ethics throughout the society, and build a cohesive force of beautiful China to win the battle of pollution prevention and control. Therefore, environmental supervisors proposed that combining the actual situations, all construction participants shall enhance the propagation of environmental protection on the construction sites, and initiate the frugal, green and healthy lifestyle and positively participate in eco-environment protection activities through meetings and bulletin boards. (6) Submitting Environmental Supervision Monthly Reports 1) Major contents of monthly reports Monthly report of environmental supervision mainly includes: i. Project overview; ii. Entrustment of environmental supervisors and the situation of the project team; iii. Construction of the project this month; iv. Main contents of environmental supervision works in this month; v. Implementation of pollution prevention facilities and ecological protection measures during the project period; vi.

x. Summary of environmental supervision in this month. 2) General condition of project monthly reports In the first half of 2020, on a monthly regular basis, environmental supervisors have submitted 1 monthly reports to Xi’an Ecological Environment Bureau, Xi’an Ecological Environment Bureau Aerospace Area Sub-bureau, Xi’an Hi-tech Zone Environmental Supervision Office, Shaanxi Provincial Environmental Supervision and Management Station of Construction Projects, Xi’an Urban Infrastructure Investment Group Limited, Xi’an City Investment New Energy Limited, Xi’an Public Transportation Corporation, and Xi’an City Public Parking Facility Construction Management Limited. (7) Environmental Supervision Meetings Site meeting is the best platform for construction undertakers, supervision company and the contractor to focus on the relevant engineering issues and solve the problems during the construction process of the project. Environmental supervisors make full use of the opportunity of weekly regular attendance of the site meeting to understand the progress of the project in detail, report the environmental problems during the construction process this week to the participants, put forward clear rectification requirements and solve the environmental problems during the construction process timely. Basically, the project has entered the final stage, so environmental supervision in the first half of 2020 did not participate in the regular site meetings. (8) Environmental Protection Publicity It is a very important work for environmental supervisors to carry out environmental protection propaganda in construction field. During the daily supervision process of the project, environmental supervisors always put the environmental protection publicity work of the construction site in an important position, earnestly carry out environmental protection publicity of the project participating units, and comprehensively and actively promote the development of environmental supervision works. During the construction of the projects, environmental supervisors have utilized the company website environmental protection publicity, regular meeting environmental protection publicity, construction site environmental protection publicity, briefing environmental protection publicity, “6.5 World Environment Day” environmental protection publicity, and other 59

methods. Generally speaking, environmental protection propaganda is carried out through multiple channels and in various forms. Through environmental protection propaganda, the environmental protection awareness of the management personnel of each construction undertaker and on-site construction personnel is enhanced, and the impact of environmental protection propaganda on the construction site is expanded and enhanced, thereby improving the environmental quality of the construction site.

APPENDIX 2 - THE PROJECT’S COVID-19 RESPONSES

Project-level COVID-19 risk assessment. The risk level in Xi’an including the project area, where the ADB project locates, was low, and people start to go back to normal life by early March 2020. At the beginning of March 2020, there was a restriction on transportation, which impacted the progress of the project. COVID-19 caused a minor increase in management costs such as sterilizing of construction sites and construction costs, including materials and labor costs. The PMO confirmed that all PMO/IAs members, contractors, and stakeholders of the project are safe as of June 2020. Considering the project geographic location and actual status, the unanticipated risks and impacts to the Project was insignificant.

Preparation of health and safety (H&S) plans. To protect the health and safety of workers as well as communities affected by the Project, in Mar 2020, all contractors prepared their respective health and safety (H&S) plan, which are part of the site-specific EMP, addressing COVID-19 health risks. These H&S plans are aligned with relevant government regulations and guidelines on COVID-19 prevention and control. The contractors’ H&S plans were reviewed by the Engineer or supervision consultant in consultation with relevant public health inspectors of the area, local medical officers and other relevant health specialists, with a recommendation forwarded to the IAs for clearance. The capacity of the Engineer or supervision consultant was strengthened or supplemented by additional government H&S technical support and training to allow them to undertake professional review, and make recommendations to the IAs and monitor such H&S plans. The IAs has undertaken to make available the necessary budgetary and human resources to fully implement EMP, including these H&S plans.

Implementation of Health and safety (H&S) plans. To cope with the COVID-19 virus impacts, the PMO/IAs and contractors have taken highly cautious control measures to effectively prevent transmission and outbreak and to efficiently safeguard their staff and field construction workers’ health and safety. No confirmed or suspected infected cases were reported so far. Since the issue is still new and the COVID-19 situation is uncertain at this moment, PMO/IAs and contractors will continue extensive communications on updated and proper measures to avoid those impacts.
